Title: | Effects of sensor errors on the performance of map matching | Authors: | Chen, W Li, Z Yu, M Chen, YQ |
Issue Date: | May-2005 | Source: | Journal of navigation, May 2005, v. 58, no. 2, p. 273-282 | Abstract: | Map matching has been widely applied in car navigation systems as an efficient method to display the location of vehicles on maps. Various map-matching algorithms have been proposed. Inevitably, the correctness of the map matching is closely related to the accuracy of positioning sensors, such as GPS or Dead Reckoning (DR), and the complexity of the road network and map, especially in urban areas where the GPS signal may be constantly blocked by buildings and the road network is complicated. The existing map matching algorithms cannot resolve the positioning problems under all circumstances. They sometimes give the wrong position estimates of the car on road; the result is called mismatching. In order to improve the quality of map matching, a deep understand of the accuracy of sensor errors on mismatching is important. This paper analyses various factors that may affect the quality of map matching based on extensive tests in Hong Kong. Suggestions to improve the success rate of map matching are also provided. | Keywords: | Map matching GPS and DR Navigation system |
